STOCK SPEC motors (13.5T-25.5T) 13.5T- 21.5T 2 POLE Super High-Efficiency brushless motor Diameter/Length (mm): Ø=35.9mm L=50.5mm Shaft Diameter/ Length (mm): Ø=3.17mm L=13.3mm 25.5T Diameter/Length (mm): Ø=35.9mm L=51.2mm Shaft Diameter/ Length (mm): Ø=3.17mm L=13mm Improved Power & RPM The optimized stator structure combined with the super magnetic rotor improves the G3R Stock motor's torque by 13.3%, KV value by 6.5% and maximum output power by 8.6% when compared to the V10 G3 Stock motor. The high torque, RPM and power make it a “secret weapon” for the Stock class racing. Low Resistance but High Efficiency Its resistance is reduced by 11% but the efficiency is improved by 6% when compared to the V10 G3 Stock motor. The super high efficiency significantly slow down the temperature increase. Super Lightweight The G3R Stock weighs only 139g and is 8.6% lighter than some popular Stock motors (that weigh 152g) on the market. The light-weight motor allows drivers to easily control the balance of their RC vehicles. Great Heat Dissipation The special shell design which makes the stator core (/laminations) expose to the air will maximize cooling, the big holes on the front & rear end plates will guarantee outstanding heat dissipation. Re-buildable Structure The detachable structure design for regular cleaning & maintenance will effectively prolong the service life of the motor and retain its efficiency. Stock & Optional Rotors The stock super magnetic rotor(PN: 30820411) for 13.5-21.5T motor is applicable to the Blinky stock racing. Change optional titanium shaft weak magnetic rotor (PN30820416) is applicable to BOOST Stock variable angle racing, with higher power output and lower temperature of motor. High-quality Components The use of high-performance stator core (/laminations), heat(200℃)-resistant pure copper wire, heat(180℃)-resistant rotor with strong structure, world-class high precision and high strength bearings, and copper solder tabs with super current endura
